' To all whom it may concern:

Be it known that I;.SoLoMoN citizen of Australia, residing Rosalie, Brisbane, in the. btateyof Queensland,'(-ommonwealth of Australia, journalist,

WANMER,

' have invented new and useful In rovemen't's in Type-Writers. of which the fo specification. 1 a p v This invention relates to mechanism attachable to typewriters for thepurpose of returning the carriage either to the commencement of the line, 'or' toany intermediate point, and at the same time, except when otherwise desired, advancing the platen, so as to write it new line. I

The object is provide a device that is lowing is a o simple in constrllction, effective, and that jeotion on the can be adapted to almost any make ofmachine, with little ornoalteration to the lat ter. It is adaptable for use on machines having carriages of variouslengths.

In carrying out my invention, I ivot in a bearing or, bearings attached to or ormed on the front of the machine, an operating lever so placed that it can be easily manipulated by the typist, without the latter removing his or her hands from, or .far from the key board. This lever is cared, 0r articulated to another rocking sha is, pivoted in bearings attached to or formed on one side (preferably the right) of the machine' This rocking shaft carries an arm'which is in turn' connected with the carriage or with the line spacer. If desired the operating lever may be connected with a treadle, or provided with other'means, whereby it may be operated by the foot.

- In order to reduce the shock on the-marginal stop, when the carriage is pulled back, I

provide an adjustable stop suitably placed on the frame, capable of engaging with a procarriage or withthe carriage itself. F

In order that my invention may be clearl understood I will now describe it fully with drawings.

- Figure lie a perspective view illustrating an ordinary bl nd typewriter (all the de: tails which do-not afiect this'invention being omitted) fitted with my invention, the carriage returner being shown ina position to return the carriage to the commencement of the line. Fig. 2 is a similar view, but showing the-position of the carriage returner when the carriage has been returned. Fig-3 is a part view illustratinganother method by at Alice street,

A is the frame of the typewriter, at the front of which is placed an operating lever B (carried by the rocking shaft C in bearings D attached to or formed on the front of the frame) so desi nod and laced that, it can be easily operate preferab y by the wrist, orby the fingers 'or hand, of the typist without the latter removing his or her hands from or far from thekeyboard. If desired this operating lever B may be connected to a treadle or provided with astirru like attachment so that it can be'operated y the foot ofthe typist. The operating lever is so designed that it can be quickly moved out-of the Way when the cover is being put on, b *being swung back over the keyboard, or 0t erwise.

In typewriters having a fra ile front fram tached to or formed on the side of the frame A. Several other mechanical devices may be used for transferring the motion from the rocking shaft C to the shaft G, but I prefer the sectors E and F.

In Figs. 4 and 5, 1 illustrate modifications of the operating lever B and means of actu- Figs. 4 and 5 are ating the rocking shaft G. [In both of these cases the lever B is placed and pivoted parallel to the front of the machine, onehrmB of the lever, as in Fig. 5'being provided with a pin E which wi es against a cam face F car ried on the roc ing shaft G. In 4 the arm 13- of the lever is provided with a'toothed sector E which engages with a toothed sector F on the rocking shaftG The rocking shaft G is provided with an armJ connects to the line spacing lever K or carriage-L.

The arm J may be made in one piece, or it maybe made extensible so that it can be 15 well known, the changing of the line and adapted for use with carriages of different lengths, such asfoolscap, brief &c As

' ch ne; The line fer very consideraolyinthe various makes of machines. @omehaveatransverseoscillatory movement, others have a combined forward and hpward movement, while others have-a transverse horizontal movement. in some instances the said spacers-are at the right hand end of the platen, while in others it is laced at the left' hand side. It is therefore vious that, in this specificatiomitwould be impossible to describe the various adaptations.

Suflice to saythat the arm'would beso placed that while it is capable of movingthe carriage along it also advances the platen either at the commencement, during, or-at the end of the movement of the carriage; also the arm and -its connection with the spacer would be such that, in "machines wherein; the carriage is lifted to see the work, such carria e is. not unnecessarily raised while being pu ed along and at the same time such armand connectionshould not interfere with the lifting of the carriage.

In Figs. 1 and 2 is illustrated the sim lest form ofconnection between the arm and line s 'acing lever K, viz :a cord, leather or meta strap, or light rod M, the ends of which ried on the carriage is thenattached to the are attached tothe arm J and lever Krespectively. So far as I can see this form of connection is applicable to most makes of mm chine, without material alteration to the lateter, but in some machines, such as the" f Remington wherein the line spacinglever mov es forwardly and .u wardly it is necessary'that some mechanica device should be fitted so .as to change the transverse motion of thearm J .into a motion at right angles thereto; In

Fig. 3 Lillustrate one method of doing this. In this case the cord, or leather or metal strap M is attached to the arm J, and, passing over a roller or pulle N on the bracket P carline spacer K which is shaped somewhat as shown (the old shape being shown by dotted lines). In the case of machines having the line spacer on the left hand side of the carriage, the connection M would be so placed as not to interfere with the view of the writmg, particularly of writing in sight mas In the foregoing 'I have described my mechanism as being attached at various points to the frame A. It will however be understood, that, if desired, the whole can be carried on a se%arate bed late attachable to the frame A or ase boar by screws, clamps or other devices.

In addition to the usual marginal stop I i prefer to fit a supplementary stop either in the position shown in the drawings or at the right hand side of the carriage L, or elsew p er'e his consists of a stop Q (adjustably atsto tached tothe frame A by the thumb nut R) jointed at .S, and provided with an inclined shown in the drawings.

spacers and their action dif" faceat' T. This stop engages. with the hinged projection U carried on the carriage Lv preferably providedwith a spring which tendsto keep it in its normal pos tion as Marginal notes meiv be made by' raising the' proi'fection U an allowing it to pass over T. "desired the stop-Q may engage direct with the carriage L, means being rovided whereby it may be depressed, (such as by the marginal release) when it is necessary to make a marg nal note. I

It will vbe-understood that the details of carrying out my invention ma be varied according to re uirements and t e make of the machine to which it is applied, without deartingfrom the general rinci lee.-

. earings may be provided ifesire The mode of operation. is as follows Starting with the machine with the carriage L, at the end of the line as shown in Fig. 1, the operating lever B is depressed by means of the wrist or otherwise, thus causing the shafts ,C and G to rock and swing over the arm J, and'thus move over the carria e L to the commencement of the line as in ig. 2. The platen V is advanced at the commence- Ball I ment, during, or at the end of the movement of the carriage, or the carriage may be moved along-without advancing the platen, according tothe manner of applying the pressure which is put on the operating lever D.

Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declarethat what I claim is 1. A typewriter comprising a carriage, a lever for turning the platen and returning the carria e to starting position, a vertical lever, a flexi 1e connection from'the upper end of said lever to the lever on thecarriag'e, a horizontal shaft on the side of the typewriter having its end secured to the lower end of the verticallever, a. horizontal shaft on the front of the type writer, gears on the adj acent ends of said horizontal shafts meshing with each other, andmeans for rocking the shaft on the hour of the typewriter.

2. A typewriter comprising'a carria e, a

hinged stop on.the same, a slotted sli e, a thumb screw passing through the slot in saidslide and into the typewriter, and a sto Q composed of spring metal having one en secured to said slide and pg-ojecting upwardly at an incline so as to e on aged by the hinged sto so as to act as a bu er to limit the,

return oft ecarriage. v I

In testimony whereof Ihave signed my name to this specificationm the two subscribing wltnesses.
